To determine whether antithrombin (AT) administration during cardiopulmonary resuscitation (CPR) increased cerebral circulation and reduced reperfusion injury. ⋯ In this experimental model of CPR, AT administration did not increase cerebral circulation or reduce reperfusion injury after ROSC.

Case Reports
Successful thrombolysis after pulmonary embolectomy for persistent massive postoperative pulmonary embolism.
Massive postoperative pulmonary embolism (PE) is associated with a poor prognosis in patients presenting with haemodynamic instability. Since recent surgery is a commonly accepted contraindication for thrombolytic therapy, pulmonary embolectomy is an appropriate therapeutic approach in these patients. ⋯ During and after thrombolysis, no bleeding complications occurred. We conclude that low-dose thrombolysis for PE may be considered even in patients who have recently undergone major thoracic and abdominal surgery if embolectomy and continued intravenous heparin have failed to be successful and life-threatening symptoms of PE persist.

In-hospital cardiopulmonary resuscitation (CPR) has seen a steady increase in the application of technology and techniques since the introduction of closed cardiac massage in 1960. Despite this progress, there has not been a demonstrated improvement in survival rates after in-hospital cardiac arrest over the last 40 years. Identification of prognostic factors associated with survival after a resuscitation attempt can help physician decisions and patients' end-of-life choices in a pre-arrest situation. ⋯ Survival after in-hospital cardiopulmonary arrest is poor and can be estimated by using clinical variables. If validated in a large prospective trial, this score could help physicians in attempting resuscitation, patients and families in making end-of-life decisions and hospitals in resource allocation.

Carbon monoxide (CO) poisoning is the most common form of lethal poisoning. The aim of this prospective clinical study was to assess the possible role of S100B, the structural protein in the astroglia, as a biochemical marker of brain injury in carbon monoxide poisoning. Serum S100B determination was performed in 38 consecutive patients poisoned by carbon monoxide who were admitted to the Emergency Department (ED) in Ljubljana. ⋯ S100B was elevated in two of the six patients with initial transitory unconsciousness at the scene. All 29 patients without loss of consciousness had normal S100B levels. Carbon monoxide poisoning appears to be associated with elevated S100B levels.

Randomized Controlled Trial Clinical Trial
A pilot randomised trial of thrombolysis in cardiac arrest (The TICA trial).
The outcome after out of hospital cardiac arrest is dismal. Thrombolysis during CPR has been advocated. Our hypothesis was that early administration of bolus thrombolysis could lead to improved survival from out of hospital cardiac arrest. ⋯ In this pilot study, we found the use of early bolus tenecteplase for OHCA to be feasible, and that it appears to increase the rate of ROSC. Larger studies are required to determine if this translates into a survival benefit. Appropriate patient selection for OHCA studies remains problematic.
